The legal and regulatory framework for the EU’ shale gas exploration and production regulating public health and environmental impacts [PDF]

, 2016
Shale gas has now become a major competing source of energy in the international energy mix scenario. In the European Union, the ‘‘fracking’’ which is the technique of extraction shale gas is facing very strong opposition based on the associated ...

Geological factors controlling high flowback rates of shale gas wells in the Changning area of the southern Sichuan Basin, China

Frontiers in Earth Science
In the Changning block of the southern Sichuan Basin, the shale gas wells in the Upper Ordovician Wufeng Formation to Lower Silurian Longmaxi Formation (Wufeng–Longmaxi) demonstrate significant difference in flowback rate of fracturing fluid, given the ...

Nonlinear Fractal Flow Model of Fractured Vertical Wells With Stimulated Reservoir Volume Considering the Quadratic Gradient Term

Geofluids
Although various fractal flow models have recently been developed to investigate pressure responses of fractured vertical wells, almost all of the existing fractal models ignore the quadratic gradient term (QGT), which makes them violate mass ...

Molten‐Salt‐Mediated Chemical Looping Oxidative Dehydrogenation of Ethane with In‐Situ Carbon Capture and Utilization

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
A sustainable alternative to steam cracking, the molten‐salt‐mediated oxidative dehydrogenation (MM‐ODH) of ethane (C2H6) in Li2CO3‐Na2CO3‐K2CO3 (LNK) couples thermal cracking with melt‐mediated CO2 capture to realize commercially competitive C2H4 and CO yields. LNK composition strongly influences MM‐ODH process outcomes.
